Functional and Application Differences
- Core Differences:
NSX100F: Suitable for protecting load circuits with a maximum current of 100A or below, such as small motors, lighting distribution, and small distribution boxes.
NSX160F: Suitable for protecting load circuits with a maximum current of 160A, ideal for medium-sized motors, high-power equipment, and main distribution boxes.
- Trip Unit Compatibility:
– Both support thermomagnetic (TMD) and electronic (Micrologic) trip units.
– They share the same tripping characteristics and provide overload and short-circuit protection.
- Application Scenario Comparison:
NSX100F: Suitable for small industrial equipment, branch circuits in commercial buildings, and main distribution boxes in residential buildings.
NSX160F: Suitable for medium-sized industrial machinery, floor distribution boxes, small production lines, and scenarios requiring larger current capacity.
Selection Recommendations
– Choose NSX100F: When the maximum circuit current is ≤ 100A and switchgear space saving is required.
– Choose NSX160F: When the maximum circuit current is ≤ 160A, especially for current ranges between 100A and 160A.
요약: Both NSX100F and NSX160F belong to Schneider Electric’s NSX series, with similar core technologies and functions. The key differences lie in frame current (100A vs 160A) and physical dimensions (width). The selection should be determined based on the actual load current and switchgear space.
